What should I do if I can't get along with my classmates?

People who live in society can't expect to get on well with everyone. There must be someone who is against you for various reasons. Whether or not to be friends with you is each other's business, not yours. You can't influence other people's ideas. Everyone likes to associate with people who are kind to themselves. When they start to be kind to others, they may be ungrateful, but they must persist and be gentle, which will definitely melt the gap between them and become friends. As for the eight-character problem, I think it has something to do with interpersonal communication, but it should not be the main thing for you.
